Definitions

  • the present invention relates to a smokeless article for oral consumption, and a method of manufacturing a smokeless article for oral consumption.
  • Smoking is generally considered to expose a smoker to potentially harmful substances. It is generally thought that the majority of the potentially harmful substances are formed by the heat generated during burning (combustion) of the article. There is interest in so-called heat not burn products, which heat a tobacco or similar substrate at a lower temperature than a conventional cigarette. These products are usually described as less harmful than conventional cigarettes. Both conventional cigarettes and heat not burn products are visible during use and produce smoke or vapour.
  • Smokeless articles are a suitable alternative because they do not require heating for substance delivery to the user. Instead, smokeless articles rely on saliva to extract soluble substances, typically nicotine and/or flavours, from tobacco contained within the smokeless article.
  • Conventional smokeless articles have a saliva permeable pouch housing a content.
  • the content is generally in the form of tobacco.
  • Such a product may be referred to as portion snus. It is typically provided as prepackaged (traditionally moist) powder in small teabag-like pouches. Each pouch is a single portion or unit. This moistened product may be referred to as original snus.
  • Smokeless articles are placed in the mouth where saliva extracts the soluble element from the tobacco contained within.
  • the smokeless article is placed in the oral cavity, sublingually or in the oral vestibule (between the teeth and lips/cheeks).
  • the user may assist extraction by oral manipulation, such as by chewing and/or sucking or pressing on the outside of the mouth to squeeze the pouch.
  • the resulting saliva which contains extracts, subsequently contacts a mucous membrane in the mouth, or at another point of the gastrointestinal tract, to deliver the soluble element across the membrane and into the bloodstream.
  • the soluble element is then transported by the bloodstream to the site of action. For example, nicotine is delivered to the brain where it acts upon acetylcholine receptors.
  • Snuff is smokeless tobacco made from ground or pulverised tobacco leaves. Snuff is available in dry form or wet (moist) form. Moist snuff may be referred to as snus. Two common varieties of snus are Scandinavian snus and American snus. Both varieties of snus are available in a loose form, but are often contained within a saliva permeable pouch.
  • snus is typically manufactured by grinding a blend of leaf tobaccos to specified particle sizes.
  • the ground tobacco is then mixed with water and sodium chloride in closed process blenders.
  • the mixture is subjected to a heat treatment, involving temperatures up to 80 - 100 °C, for several hours to pasteurize the snus. Thereafter, the snus is cooled and other ingredients may be added.
  • Snus is typically manufactured to meet the GothiaTek® standard, as detailed in " Swedish snus and the GothiaTek® standard” (2005), Rutqvist , et al.
  • content(s) is intended to refer to compounds, material and/or substances that may be enclosed within the pouch.
  • nicotine is intended to refer to nicotine, nicotine salt(s), nicotine complex(es); and/or nicotine solvate(s).
  • non-porous is intended to refer to a material that does not include any pores extending through the thickness of the wall (for instance, “through holes” or capillaries).
  • saliva-stable is intended to refer to a material that does not substantially dissolve or disintegrate as a result of exposure to saliva in the oral cavity of the user at physiological temperature. Therefore a layer of such material is resistant to the migration of saliva (or compounds/substances dissolvable in saliva, for example nicotinic compounds) through the thickness of the material.
  • the material may also be resistant to migration of saliva (or compounds/substances dissolvable in saliva e.g. nicotinic compounds) by phase transfer mechanisms. In some cases a standard commercially available artificial saliva may be used to test saliva-stability.
  • “saliva-stable” may equate to “water-stable” and refer to a material that does not substantially dissolve or disintegrate as a result of exposure to water in the oral cavity of the user at physiological pH.
  • a layer of the material is resistant to the migration of water (or compounds/substances dissolvable in water, for example nicotinic compounds) through the thickness of the material.
  • the material may also be resistant to migration of water (or compounds/substances dissolvable in water e.g. nicotinic compounds) by phase transfer mechanisms.
  • saliva is intended to refer to the liquid substance formed in the mouth of animals, such as humans, that includes water, electrolytes and enzymes. Other components of saliva may include mucus, white blood cells, epithelial cells and/or antimicrobial agents.
  • hydrophobic is intended to refer to a material having water contact angle greater than 90°, such that the material is resistant to adsorption and/or absorption of water. In some instances such material may have a polarity lower than that of water.
  • plant material is intended to refer to a portion and/or part(s) of a plant (e.g. leaf, stem, flower or bud).
  • the plant material may be processed (for example, by shredding, grinding or drying) or it may be non-processed (that is, used whole).
  • the plant material is typically fibrous (comprising or characterised by fibres).
  • plant material is not intended to include pulp and/or paper which is derived from a plant material (typically wood) and chemically and/or mechanically processed to extract fibres before use.
  • moisture content may include water, humectants, liquid flavourants and/or other liquid compounds.
  • oral consumption is intended to refer to any oral administration route achieved by placing the smokeless article into the oral cavity. This includes, but is not limited to, buccal, sublingual, periodontal, gingival and ingestion.
  • a smokeless article for oral consumption comprising a pouch, the pouch comprising a porous substrate enclosing a content, the content comprising a nicotinic compound, wherein the porous substrate has a continuous coating of a non-porous, saliva-stable material, and wherein the coating is frangible, such that in use the coating fractures on chewing.
  • the coating of a non-porous, saliva-stable material prohibits migration of saliva (or water) into the content of the pouch.
  • the non-porous, saliva-stable material also acts to prohibit migration of the nicotinic compound from the content of the pouch into the user's oral cavity. Therefore, release of the nicotinic compound from the pouch into the user's oral cavity is prevented.
  • the frangible nature of the coating enables the user to bite down or chew on the pouch to break the coating. This exposes a portion of porous substrate that was previously covered by the coating, and facilitates migration of saliva (or water) from the user's oral cavity into the content of the pouch.
  • the saliva extracts soluble components contained within the content (in particular, the nicotinic compound), and delivers the extracted components from the pouch into the user's oral cavity.
  • the user has complete control over when the release of the nicotinic compound is initiated. For instance, when a nicotine "hit" is desired by the user, they can simply bite down on the pouch to break the frangible coating and initiate release of the nicotinic compound.
  • the presence of the continuous coating of non-porous, saliva-stable material imparts an additional benefit that the loss of moisture from the content of the pouch prior to use is retarded.
  • the coating retards or prevents the passage of moisture with the result that the rate of loss of moisture from the content over time is reduced as compared to a smokeless article having no such coating or in which the coating is breached; providing a smokeless article having a longer shelf-life.
  • the coating is located on an inner surface of the porous substrate; in some cases exclusively on the inner surface of the porous substrate.
  • the coating is shielded from premature breakage as it is contained on a surface that is within the enclosed volume of the pouch.
  • the coating is located on an outer surface of the porous substrate; in some cases exclusively on the outer surface of the porous substrate.
  • the coating may provide an improved mouth-feel to the user because, in use, the coating is in direct contact with the user's oral cavity.
  • the coating may provide a surface that feels smoother against the user's oral cavity e.g. as compared to the porous substrate.
  • inner surface is intended to refer to the surface of the porous substrate that is closest to the content contained within the pouch.
  • outer surface is intended to refer to the surface of the porous substrate furthest away from the content contained within the pouch.
  • the non-porous, saliva-stable material comprises a polymer.
  • the physical properties of the non-porous, saliva-stable material can easily be tuned by selection of an appropriate polymer. This is advantageous from a manufacturing and processability perspective. It is also advantageous from the perspective of use of the article. For example, the degree of frangibility of the coating can be tuned be selection of an appropriate polymer.
  • the polymer is selected from sorbitol, maltitol, isomalt, mannitol, starch, gelatin, gum arabic, polyvinyl acetate, carob bean gum, refined paraffin wax, shellac, locust bean gum, petroleum wax, terpene resin, tragacanth, polyethylene, xanthan gum, and combinations thereof.
  • essentially the entire enclosed volume of the pouch is defined by the porous substrate.
  • the non-porous, saliva-stable material is hydrophobic.
  • the coating more effectively repels saliva (or water) to prevent the migration of saliva (or water) through the porous substrate.
  • the content is tobacco-free.
  • the user may experience a similar or enhanced recreational/pharmaceutical effect as compared to conventional tobacco-containing products without experiencing undesirable components inherent to tobacco (e.g. tobacco flavour).
  • tobacco flavour undesirable components inherent to tobacco
  • the coating may be applied to the porous substrate by any suitable means, for example, brushing, spraying, or immersion. It is preferred that the coating is uniform across a surface of the porous substrate.
  • the coating is applied by spray coating.
  • a smokeless article for oral consumption comprising:
  • the coating material may be applied to the sheet of a porous substrate on a surface intended to be the inner surface of the porous substrate when it is made into a pouch.
  • the coating material may be applied to the sheet of a porous substrate on a surface intended to be the outer surface of the porous substrate when it is made into a pouch.
  • the coating material may be applied to both of said surfaces.
  • the coating material is typically applied to the porous substrate sheet in a spreadable or sprayable state, for example as a liquid or paste. After application, the coating material then becomes frangible over time, for example upon curing or evaporation of solvent. In some cases the coated sheet of porous substrate is formed into a pouch before the coating material becomes frangible, this reduces the incidence of cracking or other breaching of the coating upon formation of the pouch. This may involve formation of a pouch that is still open along at least a portion of at least one side to allow contents to be filled into the pouch, or it may involve complete formation and filling of the closed pouch before the coating material becomes frangible. As such the method may further include a step of curing or allowing solvent to evaporate from the coating material to form a frangible coating. This step may occur between steps (i) and (ii) above; or between steps (ii) and (iii) above; or following step (iii) above.
  • step (ii) the coated sheet of porous substrate is arranged such that the coating of the non-porous, saliva-stable material is provided on an inner surface of the porous substrate.
  • the coating material is applied by spray-coating.

A nicotinic compound within the content 14 is then extracted into the saliva and may enter the user's blood stream by oral consumption to provide a nicotine "hit".
  • FIG 2 shows a second embodiment of a smokeless article 10' having a pouch 12, the pouch being a porous substrate having an inner surface 17 and an outer surface 18.
  • the pouch 12 contains a content 14 including a nicotinic compound.
  • the pouch 12 is substantially circular.
  • the pouch 12 is formed from two opposing sheets of a porous substrate and is substantially filled by the content 14.
  • the pouch 12 has a circumferential seal 16 along the edges where the two opposing sheets of a porous substrate meet to seal the contents 14 in the pouch 12.
  • the outer surface 18 of the porous substrate has a continuous coating 19 of a non-porous, saliva-stable material surrounding the pouch 12. The coating 19 being frangible.
  • Figure 3 shows a third embodiment of a smokeless article 10" that, like the first embodiment, has a pouch 12 made from a single sheet of a porous substrate.
  • one of the three seals 16' is formed by an overlap of the inner surface 17 and the outer surface 18 of the single sheet of porous substrate to seal the contents 14 in the pouch 12.
  • the remaining two seals at opposing ends of the pouch are formed where the inner surface 17 of the single sheet of porous substrate meets itself.
  • the inner surface 17 of the porous substrate has a continuous coating 19 of a non-porous, saliva-stable material between the content 14 and the pouch 12.
  • the coating 19 being frangible.
